Francis has been frequent in using his platform to address issues of mass immigration

Speaking to a broad audience at the Vatican, the Pope said: “Our differences are not a detriment or a danger; they are a source of richness. As when an artist is about to make a mosaic: it is better to have tiles of many colors available, rather than just a few."

“The experience of families teaches us this,” he added.

“as brothers and sisters, we are all different from each other. We do not always agree, but there is an unbreakable bond uniting us, and the love of our parents helps us to love one another,” he continued

Francis then addressed the 'side effects' of materialism.

"Insatiable greed marks all human history, even today, when, paradoxically, a few dine luxuriantly while all too many go without the daily bread needed to survive,” he said.
